EFFECT OF THE INVENTION

The oxazolidinone derivative, triazacycloheptane derivative or oxadiazepane derivative of the invention is useful as a pharmaceutical active ingredient (e.g., antimicrobial) or a synthetic intermediate thereof. Also, the oxazolidinone derivative of the invention has a potent antimicrobial activity against gram-positive bacteria and gram-negative bacteria. Especially, the compound exhibits antimicrobial activity with wide spectrum against drug-resistant gram-positive bacteria, including methicillin-resistant Staphylococcus aureus (MRSA), vancomycin resistant enterococcus (VRE), penicillin resistant pneumococcus (PRSP). More preferably, the compound of the invention is effective against linezolid resistant (LZD-R) organisms. The compound of the invention more preferably shows good solubility or absorbability, which allows administration by injection. Still more preferably, the compound of the invention reduces the side-effects concerned in conventional antimicrobial agents (e.g., linezolid), such as bone marrow suppression, monoamine oxidase (MAO) inhibiting activity, neurotoxicity. Decreased MAO inhibition is preferred because side-effects such as metabolism suppression of dopamine, serotonin, etc., blood pressure elevation, agitation, etc. are concerned by such inhibition. Additionally, preferred compound of the invention also shows good profiles in pharmacokinetics such as CYP inhibition, PK profile, plasma stability.

Also, the compound of the invention, wherein triazacycloheptane skeleton or oxadiazepane skeleton is connected to quinolone skeleton, shows a potent antimicrobial activity against various bacteria. Especially, the compound shows antimicrobial activity equal to or more (e.g., more than 4 times) than commercial newquinolone antimicrobial drug (e.g., ciprofloxacin, gatifloxacin, moxifloxacin) against various bacteria including VRE (vancomycin resistant enterococcus), MRSA (methicillin-resistant Staphylococcus aureus).

Thus, by having triazacycloheptane skeleton, oxadiazepane skeleton or similar structure thereof as a partial structure, the compound of the invention remarkably improves its pharmaceutical activity, pharmacokinetics and/or side-effects and very useful as a pharmaceutical compound.

Also, a synthetic intermediate of the invention having triazacycloheptane skeleton, oxadiazepane skeleton is useful for the production of various pharmaceutical compounds including antimicrobial agent.

Synthesis of Compound (44)

To a solution of hydroxylamine-BOC compound (4.01 g) in DMF (40 ml), 60% NaH (2.61 g) is added portionwise at room temperature, and effervescence occurs simultaneously. After 15 minutes, mesyl compound (11.59 g) in DMF (40 ml) is dropped slowly, and stirred at room temperature for 15 minutes. The temperature is raised to 100-110° C. and continued stirring carefully for additional 15 minutes. After the reaction, under reduced pressure, solvent is removed and NH₄Cl aqueous solution is added and extracted with ethyl acetate. After dryness (Na₂SO₄), solvent is removed, and the residue is purified by silica gel chromatography (hexane-ethyl acetate (2:1)) to afford Compound (44) (6.11 g, 62%) as a colorless oil.

44: colorless oil; ¹H-NMR (300 MHz, CDCl₃) δ 1.48 (s, 9H), 3.56-3.75 (m, 6H), 3.94-4.05 (m, 2H), 5.14 (s, 2H), 7.32 (s, 5H); IR (CHCl₃) ν_(max) 1693 cm⁻¹; MS e/m 277 (3), 206 (3), 115 (10), 101 (29), 91 (99), 57 (100).

Synthesis of Compound (45)

To a solution of oxadiazepane compound (44, 6.84 g) in methanol (70 ml), 10% Pd—C (1.01 g) is added to subject to hydrogenation for 6 hours. After the reaction, the mixture is filtered, and solvent is removed. The residue is purified by silica gel chromatography (chloroform-methanol (9:1)). Recrystallization from ethanol affords a colorless amorphous Compound (45) (2.80 g, 68%)

45: colorless amorphous mp: 156.5-157.5° C. (EtOH) (decomp.);

1H-NMR (300 MHz, CDCl₃) δ 1.51 (s, 9H), 3.41-3.53 (m, 4H), 3.99 (t, 6, 2H), 4.32 (t, 5, 2H)); IR (KBr) ν_(max) 1705, 1667 cm⁻¹; MS e/m 202 (M⁺, 1), 129 (9), 99 (12), 72 (17), 57 (100), 43 (86).

Synthesis of Compound (46)

To a solution of amine compound (45, 6.84 g) and 3,4,5-trifluoronitro benzene (3.11 g) in acetonitrile (60 ml), potassium carbonate (3.19 g) is added, and the mixture is heated at reflux for 15 hours. After the reaction, NH₄Cl aqueous solution is added mad extracted with chloroform-methanol (9:1). After dryness (Na₂SO₄), solvent is removed, and the residue is purified by silica gel chromatography (hexane-ethyl acetate (2:1)). Recrystallization from hexane affords 3.31 g (52%) of Compound (46) as yellow needle-like crystal.
